Description
This swing Check Valve (Screwed in Cover, Class 150, Flanged) from Leader covers 15 mm to 100 mm. Fitted to prevent flow reversing when a pump stops or a line depressurises. Orientation matters: a swing pattern needs the correct attitude to seat properly, so confirm the intended mounting before ordering. Flanged ends make the valve straightforward to remove for servicing without cutting pipe, and are the norm once bore and weight rule out threaded joints. Used on pump delivery lines and wherever two sources feed a shared main. Size-by-size catalogue numbers and pricing appear in the table above.
